Currently available for ordering through your local comic shop, Diamond Select has three neon signs based on iconic images from the Marvel Universe -- Iron Man's mask, Captain America's shield and the famous classic Marvel logo. Each sign measures nearly a foot in diameter, and comes with a base for mounting on the wall or standing on any flat surface. Also still available is DST's popular Ghostbusters logo neon sign, with the same customizable base. Check them all out lit-up and in action in our photo gallery below.
